9... d8c7  10. c1f4 The fourth most popular move. Nepomniachtchi, as do all elite players, has his own views on opening theory. 10... g8e7  11. a2a4 A logical move, preparing the development of the knight on a3, but it's not clear how White will react when Black plays a7-a6. It seems to me that both players confused the move order in the opening, which is not surprising; after all, this is a blitz game. 11... e8c8 This move helps White's attack, since the king goes directly into the fire.
